The Duology of 3D Spu7Nix Levels: HOW and WHAT

Truth to be told, I never played HOW until now. Perhaps there will be more additions to this "series" in the future :D
Level name: HOW, WHAT

Geometry Dash is a rhythm-based platformer game developed and published by RobTop Games. It was released for $1.99 USD on August 13, 2013 for iOS and Android, and for $3.99 USD on December 22, 2014 for Steam. A lite version of the game is available on mobile devices with fewer features, as well as free expansions, Geometry Dash Meltdown, Geometry Dash World and Geometry Dash SubZero, which include exclusive levels.
The player takes the form of different entities with unique mechanics such as a cube, a ball or a UFO. Using one-touch gameplay, the player must try to navigate through a series of interactive obstacles, movement-shifting transporters and behaviour-manipulating portals to reach the end of levels without crashing, all while listening to exciting soundtracks along the way.
